JS2Support as an extension, includes AddMediaWizard, UploadWizard, UsabilityJS2, and TimedMediaHandler Extensions

All sandboxes are running the same core software and using the same database, but each have a unique configuration and set of extensions, so any edits to one of the sandboxes will render the edit to the other ones as well.

Feedback

Comments should be posted to the sandbox discussion page. Bugs should probably not be reported since the software running on these servers is expected to be experimental.
